at the apex, "basal portion along with the suhicuhim pul-

Hydnum melleum, B. & Br., Ann. Nat. Hist., n. 1436 ; 

 Stev., Fung., p. 244. 



On fallen rails. Forming an exceedingly thin lioney- 

 coloured film, margin minutely byssoid. Spines about 1 line 

 long, often scattered, stout and blunt or slender and acute, 

 or again, blunt and divided at the apex. At best but a 

 doubtful species of Hijdnum. 



Hydnum sepultum. B. & Br. 



Eesuj)inate, golden-yellow, margin white ; sj)ines acute, 

 medium-sized ; spores globose, 5 /x diameter. 



Hydnum sepultum, B. & Br., Ann. Nat. Hist., n. 1813 ; 

 Stev., Fung., p. 244. 



On stones buried amongst pine leaves. Forming little 

 scattered patches ; spines about 1 line long. Distinguished 

 from other resupinate yellow species by the persistent, white, 

 sterile margin and the globose spores. 



*** Sj^ines flesh-colour, lilac or rufescent. 



Hydnum udum. Fr. 



Flesh-colour, then pale yellowish, subgelatinous, effused 

 for several inches ; spines crowded, unequal, about 1 line 

 long, awl-shaped or compressed, simple or toothed, coloured 

 like the subiculum. 



Hydnum udum, Fries, Syst. Myc. i. p. 422 ; Stev., Fung., 

 p. 24.5. 



Forming elongated, dingy, subgelatinous expansions on 

 dead branches ; not separable from the wood. Forming- 

 elongated patches 4—5 in. l<mg. My specimens agree 

 with Fries' character in every respect, except that most of 

 the spines are simple. When dry it is yellowish towards the 

 margin, the more central parts being of a pale fawn colour.
